Ohm meters

[Spizzel]

I'm in the process of getting supplies to start rebuilding and I've been getting items slowly in the mail. Yesterday my eleaf ohm reader came and it seems to be off by .1 ohm sometimes a little higher. I will be building nickel targeting around .15 to .2 so for it to be off by that amount seems bad.

I have 2 nautilus minis with 1.6 ohm coils and checked both on the eleaf, said 1.7 ohms for both. Then put both on my Hana and that read them as 1.59 and 1.6.

It advertises accuracy within .04 ohms but seems off by .1, is that typical behavior for some of these cheap ohm meters?

I would never trust a cheap ohm meter for anything that is 4" from my face at any point in time...

I really can't tell how accurate my eleaf is. The mods I have access to read the next higher value. IE: eleaf says 1.27, mods say 1.3 although think my Vamo might have rounded down last night. Eleaf said 1.33, Vamo said 1.3.

Could you recommend one that isn't 'cheap'? I'm not against spending some bucks but all I see are the little chepo black ones when I look around.

Well, at least it seems as though your eleaf ohm meter is close. Mine is off by a fair amount :/ It had decent reviews but seems like I got what I pad for. Should of guess a $8 meter may not be up to snuff hah

Actually, I use two meters with my mech. My vv/vw MODs have resistance checkers, too. I don't think I will ever trust just one meter, no matter the quality level.

USA ohm meters seem to be among the best out there. I just got one yesterday. My Smok one went bonkers a few weeks ago and went into the garbage. It was only a few dollars more for the new one.

I only got a little over 3 months use out of the Smok,which wasn't a cheap meter.

USA ohm meter seems to be the one I've seen most recommended in some other threads. Too bad I just didn't go with one to start, at least it was a cheap lesson learned and not an expensive one.

The old analogue Ohms meters had a zero-Ohms adjustment - most DMMs don't.

Are you taking into account the resistance of the test leads? - touch the prods together and note the reading, then subtract that reading from anything you measure.

Unless you paid half the price of a small car for the DMM, and get a calibration certificate for it once every year - I wouldn't worry about it being 0.1 Ohm out.

Agree 150%. Invest in a better multi-meter and carefully learn how to use it. They have many other uses around the house and car that will help you troubleshoot and save you money in the long run.

Also agree 150% (Damn, I'm just so damn agreeable today......)

When I wind a coil I usually aim for somewhere between 1.2 - 1.4 Ohm, the manufactured ones are 1.8, 2.4 & 2.8 - from what I read on this forum, a lot of people are going for sub-Ohm coils.

On reflection I think the error will have to be slightly more than 0.1 Ohm to level half a block.
